By March 2022, review publishers had absorbed two rounds of Google guidance: the April 2021 questions about expertise and original research, and the December 2021 push for hands-on evidence and multiple sellers. The third product reviews update, which began on 23 March 2022, added something new — guidance aimed squarely at the format affiliate sites rely on most: the ranked "best" list.
Google explained how it wanted roundups, comparisons and "best overall" picks to justify their claims, and how ranked lists should relate to in-depth single-product reviews. For many affiliate publishers, that meant rethinking roundup pages that had been built as short blurbs plus buy buttons.
This post covers the confirmed dates and scope, the exact additions to Google's guidance, how affiliate publishers could respond in practice, and where the update sits in the run of reviews updates.
Key Takeaways
- The March 2022 product reviews update began on 23 March 2022 and was complete as of 6 April 2022, according to Google's Search Status Dashboard (14 days).
- It was the third product reviews update and, like earlier ones, applied to English-language product reviews.
- Google added guidance for ranked lists and comparisons, "best" recommendations, and combining roundups with in-depth single reviews.
- Ranked lists must have enough useful content to stand on their own; "best" claims should be backed with first-hand evidence.
- Google described it as separate from core updates, while its core update quality advice still applied.

The dashboard incident page says "Released the March 2022 product reviews update" and "The rollout was complete as of April 6, 2022." Search Engine Land’s launch coverage reported that Google expected most ranking volatility early in the rollout.
What Was Added to the Guidance
Google restated its existing advice — in-depth details such as pros and cons, evidence from people who've used the product, unique information beyond the manufacturer's material, and comparisons with competitors — and then added three new areas.
| New guidance area | What Google asked for | Practical meaning |
|---|---|---|
| Ranked lists and comparisons | Show expertise concisely because these pages are shorter — for example citing relevant results or including original test images | Each list entry needs a real reason it is there |
| "Best" recommendations | Explain why a product is best overall or for a purpose, what sets it apart, with first-hand supporting evidence | "Best" must be earned, not asserted |
| Ranked lists plus single reviews | You can pair a ranked list with in-depth single-product reviews, but the list needs enough useful content to stand alone | Don't rely on the linked review to do all the work |
The same principles remain in Google's current guidance on writing high-quality reviews:
“Ensure there is enough useful content in your ranked lists for them to stand on their own”

For "best" picks, Google's documentation still says to "include why you consider it the best, with first-hand supporting evidence."
What Affiliate Publishers Could Change
Google did not publish impact data, and we have no verified figures on how many sites gained or lost. What the guidance did make clear is which formats were under the microscope. A roundup page following the March 2022 guidance typically looks different from a pre-2021 roundup:
- A short methodology summary at the top explaining how products were tested or chosen.
- A "why we picked it" explanation for each entry, ideally with a measurement, an original photo or a first-hand observation.
- Clear category winners ("best for small kitchens", "best budget option") with the reasoning stated.
- Honest drawbacks for each pick, not just positives.
- Links to in-depth reviews for readers who want more, while keeping the list useful by itself.
- Fewer, better entries rather than long lists padded with products nobody tested.

Step-by-Step: Upgrading a "Best X" Page
- Pick one high-value roundup that lost or is at risk of losing traffic.
- Check each entry: could a reader tell why it was chosen without clicking anywhere else?
- Add evidence: original images, short test results or first-hand notes for every entry.
- Justify the top pick in a short paragraph explaining what makes it best and for whom.
- Remove untested filler entries or clearly label them as researched rather than tested.
- Link to full reviews where they exist, and label affiliate links correctly with
rel="sponsored". - Measure by template after the change, comparing roundups with single reviews in Search Console.

How to Tell Whether This Update Affected You
Reviews updates only concern review content, so the first test is simple: did the pages that changed between 23 March and 6 April 2022 actually contain product reviews, comparisons or roundups? If your losses were spread across informational guides, category pages or news, something else is more likely to be responsible.
Next, segment by template. Many affiliate sites have three distinct page types — single-product reviews, head-to-head comparisons and "best X" lists. Because the March 2022 guidance focused heavily on lists and "best" claims, a drop concentrated in roundups while single reviews held steady is a strong hint. Our guide to template-level update analysis shows how to set up those segments in Search Console using URL patterns.
Finally, look at who replaced you. If the pages now ranking for your lost queries show testing evidence, clear reasoning for each pick and honest drawbacks, you have a concrete gap to close.
How It Fits the Bigger Timeline
March 2022 was the third in the series after April 2021 and December 2021. It began about three weeks after the desktop page experience update completed, and two months before the May 2022 core update. The next reviews update came in July 2022. Google's current reviews system documentation now covers 11 languages and says the system is improved on an ongoing basis.
Common Mistakes
- Calling something "best" without saying why. Google specifically asked for the reasoning and evidence.
- Thin roundup entries that rely on links to full reviews to provide any substance.
- Padding lists with products you didn't test just to target more keywords.
- Copying spec tables from manufacturers instead of adding original insight.
- Over-attributing drops to this update — check whether your affected pages are actually reviews.
